Error in Abstract

The Original Investigation titled “Association of Opioid Agonist Treatment With All-Cause Mortality and Specific Causes of Death Among People With Opioid Dependence: A Systematic Review and Meta-analysis,”¹ was corrected to fix an incorrectly reported rate ratio in the abstract; in the line “In the first 4 weeks of methadone treatment, rates of all-cause mortality and drug-related poisoning were more than double the rates during the remainder of OAT (RR, 2.81; 95% CI, 1.55-5.09),” the rate ratio had mistakenly been reported as 2.01. This article was corrected online.
